T0 -ALL WHOM-IT lMAY OONCERN: j

Be itknown that I, RUFUSBRUNSO, of the city of Chicago, county lot' Cook-,and 'Statfc of Illinois, have invented an, Improved Hand-Press for Pressing Bricks, which I style the Diamond-Shaped Press and I do hereby declare the following to be-'nn exactldescription thereof, reference being had tol `the accompanying drawings, andto theletters ofreference markedthereon, making a part'of this specieation. in whch= I `Figure 1 represents a vertical section. i Figure 2, a side elevation; i

Eigure 3, the jointed plates, with a plainlei er to 'operate them and Figure4 shows a double mould forrpressing two bricks, and acentre block of wood `connecting the bricks together. A

The nature of -rny invention consists in the diamond-shaped frame, and the adjustable and jointed plates between the Frame, forming a diamond-shaped box, the plates on one side being constructed with a rack, upon which a ratchet -and lever operate, arranged'and eombinpd r-ithfan outside treadle forthe purpose ot' raising-the box containing the 'inould,and pressingl the bricks that are intended to be what are commonly called concrete bricks. i j Y A represents a platform that supports the machine; -B B are the diamond-shapcd side-plates, or upright frame ofleastirdn, between which the jointed plates G C operate; the joints are constructed on the ends o'f`the plates at D,by one plate being concave and fitting over the `ends or edges of4 the lower plates that are convex,

-so'us-to prevent any sand or dirt from settling or iilling in ,the joints; and at the bottom are grooves, E, that Y let the sand or dirt pass o', and, as the water is pressed out of. the concrete, it passes down ou the inside, and

. washes out through the groovesE. G ,is tl1e fol lo\vei,'that rests upon the top of the plat-es C, and, moving A i upwards against the brick, presses the brick into the moul'ls J. The sliding-lid K, at top, after the mould is llcd, cuts oil' the topot the brick, and cleans out the grooves L that` are -in the'top of the leide-plates B. M,

the treallc that'operates tbe 'lever N, that raises the follower G by means of the pin P, so that as the o`- bearer" or operator places his foot upon the trcadle, he raises up'the brick by the pressure, andV facilitates the remevingoffthc brickr' R is a connecting-rod attached to the centre of the jointed plates C, and to ratchet S of the main lever T, for the purpose of drawing the jointed plates C together, und forcing up the follower G to,

press the bricks, as the main lever 'T ,is pressed down, (as shown by the red li-ues at fig. 1.) The ratchet S gears into the rack Vof the opposite jointed plates C, and` gites power te the lever T. Fig. 3 shows a plain lever, T,

without the ratchet er rack,'that rnay be used as an equivalent, if Iithnk proper. lFig. 4 shows two bricks in 4the mould' J, connected together by one or two strips of wood, W,ithat,may be made by the samenmchinc, if I deem necessary. Y V

The advantages are,by the construction of the devices I gain extralpower, and'on account of the siinplicity of the machine, andlits cheapness,`its utility is. attained.

What I claim as my invention, and desire to secure byLetters Patent, is

The construction and combination. of the side-plates B, jointed plates C, with the rack YV and follower (i,

vas operated by the lever T, ratchet S, and rod it, and forming a diamond-.shaped press, as herein describcd,and

'- for the`purposes set forth.
